    printf("Input n:");
    scanf("%d",&n);
    ReadScore(score,n);
    aver=Average(score,n);
    printf("Averange score is %d\n",aver);
    return 0;
}
int Averange(int score[],int n)
{
    int i,sum=0;
    for(i=0;i<n;i++)
    {
        sum+=score[i];
    }
    return sum/n;
}
void ReadScore(int socre[],int n)
{
    int i;
    printf("Input score:");
    for(i=0;i<n;i++)
    {
